HAT-VENTILATOR.

T0 aZVww/m t may concern.'

Be it known that I,` CHARLES ROBERT lViLLrAMs, a citizen of the UnitedStates, residing at Omaha, in the county of Douglas and State ofNebraska, have invented certain new and useful Improvements .inHat-Ventilators, of which the following is a specification.

The invention relates to attachments for hats and more particularly toan attachment which may be attached to the upper edge of a .sweat bandand comprising a member hingedly connected to said upper edge of theswea band and adapted, during warm weather to engage the head of thewearer, in such a manner as to support the front of the hat spaced fromthe forehead. ily so spacing the hat from the forehead the freecirculation of air is allowed within the crown of the hat, therebyreducing the amount of perspiration emitted fionitlie pores of thescalp. The circulation of air admitted within the crown of the hat alsocausing'a rapid evaporation of the perspiration that may be emitted fromthe pores of the scalp.

A further object is to provide a pivoted member pivoted to the upperedge of the hat sweat band, said pivoted member being provided withhorizontally disposed spring arms, which are adjustable said hingedmember being` adapted to be hinged inwardly of the upper edge of thesweat band so that said arms, when it is not desirable to have the hatspaced from the forehead may be disposed between the sweat band and thewall of the crown of the hat. rJ'fhe adjustable arms being flexible, itwill be seen that the bow of the arms may be. easily reversed whendisposed between the sweat bandand the crown of the hat.

7With the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawings described and claimed, it being understood that changes inthe precise embodiment of the invention may be made within the scope ofwhat is claimed without departing from vthe spirit of the invention.

In the drawings Figure 1 is a side elevation of a hat show# ing theattachment applied thereto and the hat being held spaced from the headof the I Specification of Letters Patent.

Application filed November 12,1919. Serial No. 337,378.

Fig. 2 is a horizontal sectional view taken on line 2-.2 of Fig. l.

Fig. 3 is a detail perspective vview looking into the crown of the hatand showing the spacing -member applied to the sweat band thereof.

Fig. 4 is a detail sectional view taken on vline 4.-4 of Fig. 3.

Referring to the drawings, the numeral l designates a hat and 2 thecrown thereof. Secured in the crown is a conventional form of sweat band3 the upper edge 4 of which is free and not secured to the crown. At thepresent time hats are not provided with means for ventilating the sameexcept in some hats a series of very small perforations are provided inthe crown of the hat. It has been found that such ventilation is sosmall that it does not materially affect the. temperature within thehat, nor do these small perforations allow sufficient ventilation sothat the perspiration of the scalp of the head of the wearer mayevaporate. T o overcome these difficulties and allow a. thoroughventilation of the crown of the hat by providing means for spacing thefront of the hat from the forehead of the wearer thereby allowing theingress of air to the interior of the crown 2 substantially around theforehead of the user. .To accomplishY this result a plate 5 is securedto the outer face of the sweat band 3 said plate 5 being held to thesweat band by sewing or if so desired by cement. Passing through theplate 5, sweat band 3 and reinforcing plate (3 is a rivet 7 whichsecurely holds the plate 5 in place and also prevents, in combinationwith the plate 6 the tearing or sagging of the sweat band 3. Hingedlyconnected as at S to the upper edge of the plate 5 is a plate 9, whichplate is adapted to be pivoted upwardly, outwardly and may be disposedbetween the sweat band and the inner wall of the crown when the spacingdevice is out of use, for instance during cold weather, or when it isnot desired to ventilate the crown of the hat. Slidably mounted in ayoke 10 carried by the plate 9 are overlapping spring arms ll, saidspring arms where they overlap being provided with slidable sleeves 12adapted to maintain the overlapping ends in engagement with each other.The arms 1l are preferably made of thin steel or if desired. ofCelluloid. However, they are made extremely thin so as to reduce theirtransverse cross sectional -erai toa minimum, this for the reason thatwhen the member V9 is pivoted upwardly and Vdisposed behind Y Vthe sweatband,ls'aid arms will not take upv a considerable space. By adjustingthe I exible arms and'll inwardly or ont- `-wardly the spaces 13 throughwhichthe airV passes may be increased or diminished as Y desired. By theuse offiexible arms7` it :will

be seen that when the hinged plate 9 is dis-V posed betweenthe sweatband-andtheV wall of the hat that the flexible arms will bow intheopposite direction to that shown in Fig. 2and`conform totheshapeYof-thefhat Vand head ofthe wearer. lVhenplacing the flexible armsbehind the sweat band they 'are' preferably slidinto registration kvwitheach other so as to reducetheir length to a Y' yminimum,after which thesweat band 'may V i [From the above it will 'be V.turned out slightly`so .that the reverse bowingof the flexible arms ll may be easilyaccomplished.

spacing device is provided which may Ibe applied to any form of hat, andone wherein when thedevice is out of use it will be disposedbehind thesweat band. Y
